In the Asia and Africa, flagship of the growth of cities, the urban population will double in this period. With the cities of these continents growing at a rate of one million people per week, almost seven out of ten urban citizens are Asians or Africans 2030, the study predicted.

Also note that the poorer the region, most people tend to increase and this is not just coincidence.

How long will it still take all realize that the solution to global warming, poverty and numerous other world problems is slow population growth?

Practical example:

Take a couple of any mammals (rabbits, for example) and start its creation in a limited territory, com recursos limitados. A população desse mamífero crescerá exponencialmente no início, but at some point it will stabilize and oscillate at values ​​close to a threshold. This is because at some point there will be escasses resources (food, water, etc.), in other words, there will be competition for these resources and many will die from lack of them. The population will be forcibly limited to that maximum number, lack of resources.

Now think of the world's population, the scenario is very similar, the territory of the planet is limited, resources are also limited, if the population continues to grow unchecked will come a day when there escasses resources (in fact this is already happening in many places), with that many will die, and the population will be forcibly restricted to a certain number because those resources, and there will be many wars for these resources (as has been there for oil) and there will…

Does the human population, which is said to rationally, need to really reach that threshold to realize that there is a limit? Can they not be aware already that the population can not continue to grow?
